Consider a process in which an ideal gas changes from state 1 to state 2 in such a way that its temperature changes from 300 K to 200 K. (b) Is this process isothermal?

Hey everyone today, we are asked to determine if the following statement is true or false. So we're asked if an ideal gas changes into a different state at a constant temperature is the process. I So thermal. So let's go ahead and think about this. So what does ice a thermal mean? Exactly. And is a thermal process, as the name implies? Isso thermal means that it is independent of temperature or in other words, there is no change, no change in temperature, meaning that the temperature is constant temperature. So what does this mean? If the ideal gas changes, let's say, from water to gas, right? Water to gas or liquid to gas, not the water liquid, or we're dealing with Nigel gas. So if it goes from gas to liquid, let's say, but the temperature doesn't change temperature is constant, then this means that it is indeed, I saw thermal. It would then be an ice a thermal process. Ice a thermal, since the state is changing, but the temperature itself remains constant. Therefore, the answer to this is true. If the ideal gas changes to a different state at a constant temperature, the process is indeed, I so thermal. I hope this helps. And I look forward to seeing you in the next one
